Firewall Alias over OpenVPN

[EBG]

Hello,  I am trying to prohibit certain traffic from specific computer(s) coming in via OpenVPN.

Under Firewall -> Aliases, I created an alias for computer X, type MAC address, content [the mac address]
Under Firewall -> Rules, I create a rule to block all traffic from X over OpenVPN

This doesn't work at all; I can't find a way to use aliases for OpenVPN clients.  I've tried the mac address in upper and lower case, tried putting the rule on inbound and outbound, and tried moving the rule to the LAN interface as opposed to the OpenVPN interface.  I also attempted using the name (Aliases Type(s) = Host) with all of the permutations, and host doesn't want to work either.

Is there a way to prohibit traffic from certain OpenVPN clients?
